Alpha Centauri
Abstract
New photometric observations of Alpha Centauri A and B are reported along with the results of a reanalysis of the weak lines of Fe and Ti published by French and Powell (1975) for these stars and the solar lines of Furenlid (1979) and Hearnshaw (1977). The position of Alpha Centauri and the sun in the HR diagram is examined and the possibility of planetary systems being associated with Alpha Centauri is considered.
